Abstract

Procedure for the obtaining of 2,2-dioxygenated benzophenones and in particular 2,2 "-dihydroxyzenzophenones, without substituting or substituting the bencenic ring with one or more substituents, such as rent, alcoxyl, halogens or acil. It consists in the reaction by irradiation of a solution of aciloxibenzoatos with light of 200 to 400 nanometers, at temperatures comprised between -20ºc and the ebullición of the solvent. Polar or apolar organic solvents are used. The reaction products are separated in a silica gel column. > these compounds have applications as stabilizers against the light.
